GET /api/v1.0/financials — every revenue line Microsoft reports for your account (one row per purchase line per month, refreshed nightly from Partner Center), for payout reconciliation. Join AssetId to your SaaS MarketplaceSubscriptionId; use PurchaseRecordId + LineItemId for a single purchase line. Amounts come in three currencies (CC customer, PC your payout currency, USD) and the expected payout is estimatedRevenuePC × incentiveRate / 100. See the endpoint reference for every column.
GET /api/v1.0/usage?subscriptionId=...&from=...&to=... — Microsoft's usage report: daily metered usage per subscription and meter dimension (MeterId is the dimension id you charge with; for SaaS the subscription id is in ReferenceId). Rows are daily aggregates, not individual usage events, so reconcile daily totals per dimension against what you sent through the charge endpoint. Filters are optional; without them you get the full history.
